Fair enough, I see your point. I had some things in site.config that no one ever changes like stampsExpire, etc. So I can certainly include a few more entries on the default site.config page. There are a huge number of config options, so I'm not going to include everything, but I can edit our list to make it more useful...
Basically, I've added
homeMobile: welcome
homePage: welcome
skinDefault: default
skinMobile: mobile
skinPrint: print
timezone:
And deleted the skin, the stamps settings, and set linkrot to false by default, etc. If you want to suggest other settings that should be easily found there, let me know...
As for the skins, I really would encourage the use of site.auth.skins which gives amazing control down to the page level of what skin is used where. Very powerful. But we can start with this!
The timezone setting sets the system time to whatever locale you want, but I don't know if it changes the output of various time functions. If I need to change something else to do that, let me know. You can set your format anyway you want using strftime values, but there's probably a way to set a default format...
Cheers,
Dan
